Bronte has spoken about the inspiration she gains from her teenage brother Hamish, who has cerebral palsy.

"He's amazing, he's been through a lot in his little life, lots of surgeries and complications and he's one of those wildly optimistic people, " she told the Sydney Morning Herald.

"I always think about stuff like this when I get up behind the blocks for a race. It's not life and death and that’s something that Hamish has helped me realise.

''It's given me some perspective. It’s a swimming race and it’s really, really important to me but there’s only a few other people in the world who really care about this and no one’s going to get hurt if I fail except for maybe me, so it’s definitely helped me relax going into competitions.''
